[Q] Audio out through micro USB

I had asked a question similar to this a while back in the accessories section specifically if anyone knew how to hardware trigger the car dock mode and enable the audio out through the usb port. I hadn't gotten an answer and I can't find it anywhere else. I figured I'd ask in general since it's not a feature unique to the car dock (I'm pretty sure another Atrix 2 or Atrix 4G dock can do it as well) and I was curious if it could simply be a software trigger to enable the audio out without needing the dock (obviously you'd still need a spliced cable to allow the usb to split into the audio + charging).
So, has anyone figured out a diy method of getting audio through the usb? I think I'm going to cave and just buy a car dock (AT&T has them for $30 now from the website), but I wanted to check one last time because I prefer being able to do it myself . I assumed it was something that was triggered on the ID pin and then the data pins became left and right audio, but it may be something less passive than that.

since usb is data there is no real audio out. This car dock would have to have a DAC (digital to analog converter) in it. essentially the sound is sent in digital form to it and then it is decoded to analog to be played by the dock, not the phone. in other words you cannot just enable audio out because it does not exist

Yeah, you are right. I picked one up today and took a look inside and indeed there is definitely some active components in there. My previous phone was a Captivate, so I was used to just changing a resistor value to switch different dock modes and also have the option to have the audio L/R on pins 2 & 3. I was also hopeful since I thought the DAC would need power to work and the A2 car dock works even when not plugged into the charger.
Alas, the diy dock was not meant to be (although, I think I will still need to make my own modifications, of course ).

Car dock for Note 4 with USB & Audio out (like Infuse 4G dock)

All,
Anyone know of any car dock that has both the USB injector and can output audio through USB? I currently have the Samsung Infuse 4G dock and use it with my S3. It is very convenient to dock the phone and slide the usb connector (as opposed to plugging usb and stereo manually) and it puts the phone in dock mode, which triggers my Tasker task to run navigation, play music, etc..
I have my T-Mo Note 4 now but did not find/decide a dock that can hold the phone with the Spigen Neo hybrid case on with the usb injector like the Infuse dock.
Two docks that I looked at and might work..
iBolt xProDock (http://www.amazon.com/gp/product/B00AOCSFYC/ref=ox_sc_sfl_title_1?ie=UTF8&psc=1&smid=A1KED7QPKDBUQ7)
iOttie One Touch 2 (http://www.amazon.com/gp/product/B00JRGOKQ8/ref=ox_sc_sfl_title_2?ie=UTF8&psc=1&smid=A2FE6D62A4WM6Q)
Worst case, I would have to buy one of these. Any suggestions? What do you use?
by the way, I did look through all the suggested threads in other forums before creating this one.
Thanks.

I haven't tried my iBolt xProDock, but it *should* work. They actually took forum members here opinion when they were designing it, and designed it to work with the Note 2 / 3 with a bulky otterbox case on, so you won't have any issues with the phone not fitting.
Also, their support is awesome. Part of the dock was rubbing down over time due to wear & tear, they sent me a replacement pretty quick.

I'm not sure the Note 4 has the audio out through usb capability. My Note 2 and 3 worked perfect with the ibolt dock but when I attached the Note 4 the audio would not play through the car speakers. The option to switch the audio mode in the Accessories menu is not there anymore. I tried to use tasker to switch to external speakers but no luck.

Thanks. I decided to go with the iOttie dock, because of the telescopic arm. I have some unused nfc tags that I hope to use it with Trigger/Tasker to put the phone in car mode. I will post some pictures once I get it in 4-5 days.

I have the same issue with mine. What did you end up doing?

No luck with mine and the Aux audio either with the iBolt dock or the official samsung media dock with the HDMI/usb ports. And with the iBolt the phone has to be off centered due to the position of the volume buttons.

I'm really bummed, it looks like with the Galaxy S5 and the Note 4 Samsung or Verizon has dropped support for USB dock audio out. I tried an S5-based ROM on my Note 3 and lost dock audio-out capability, and now that I've upgraded to the Verizon Note 4, it's not even an option in settings. I tried Dock Audio from the Play Store which says hopefully "Audio redirected to dock" when you enable it but doesn't change a damn thing.
My only work-around is to use a third-party Bluetooth adapter. I have the Sony SBH52 which sounds great for a Bluetooth adapter, I just plug this into my rear audio-in ports on my MDX, you could probably get a 3.5mm male-to-male audio cable to get this to work with your 3.5mm AUX jack no problem.

I had the same issue, was pretty bummed to find out that the desk dock I was using next to my bed with my s4 wouldn't play audio through the speakers I've got set up. Did a lot of looking around and didn't find any solutions currently, but I did find out something interesting that might explain some of this- It looks like Lollipop will have native support for audio out through USB. Makes me wonder if Samsung didn't include this feature in the s5 or Note 4 because they are waiting for L to drop, and will update touchwiz to handle it at that point? I can't find any confirmation of this anywhere so it's just speculation on my part, but it does seem to make sense. Why put the time and effort into designing a feature that will be coming standard in the next rev of Android anyway?

I'm using a Fiio Kunlun E-18 Audio Amplifier and Digital Audio Converter without issue on both the Galaxy S4 and the Note 4.

Not sure why USB Audio Out would not work on the Note 4.
Perhaps the DAC is missing on a dock?

As has been stated in a few other threads, the Note 4 DOES support audio out with the use of an OTG cable and an accompanying DAC/amplifier. What it lacks is support for audio out through a standard micro-USB/auxiliary audio combo cable (like you get with many car docks), or through the aux port on desk docks like the Samsung dock for the previous gen notes and Galaxy S devices. Basically, you can't just drop the Note 4 into a dock that's connected to speakers or to your car's aux in port without adding extra hardware, which was a feature that was present in all of the previous Galaxy devices IIRC (certainly you could do it with the S4 and the Note 3). The S5 also lacks this ability. What this means is that those of us who want to charge the phone and output audio on a single cable are basically out of luck
As I said in my previous post, it looks like Lollipop will be including audio out over USB standard across all devices, so my hope is that Samsung knew this and just decided not to waste time building in a feature that would become present with the 5.0 update anyway. I haven't been able to find any confirmation of this however, and I also haven't been able to find out specifically whether the feature in Lollipop will only support audio out with an OTG cable/DAC or if it also will support audio over micro-USB the way that the S4 and Note 3 did. Guess we'll just have to wait and see!

A discussion was started about this already, the only way to get audio out is an external dac and OTG.

This may sound stupid but, can you help to eloborate more on the dac and otg thighy? Does it mean i can still utilize my ibolt xprodock for prior samsung models with my note4? This will be very interesting. On Lollipop feature, I am getting my hands itchy to test the new firmware already...

So, the answer to your question is both yes and no. You won't be able to use your iBolt with the cable that it came with, but you can get audio out through usb with some extra hardware.
What is needed is a USB OTG (On The Go) cable such as one of these: http://www.amazon.com/s/?ie=UTF8&ke...hvptwo=&hvqmt=b&hvdev=c&ref=pd_sl_qy4kwf7wh_b
and a DAC (Digital to Audio Converter) like one of these: http://www.amazon.com/s/ref=nb_sb_n...aps&field-keywords=USB+DAC&rh=i:aps,k:USB+DAC
I haven't personally done this, so I'm really not the best person to completely explain how this all works, but there is tons of info on doing this all around the web. The long and the short of it though is that you'll need the extra hardware to make this work and you won't be able to get the dock recognition that you get from the iBolt cable.

This problem can be solved with a modified kernel?

So. It can be done? Will I be able to charge the phone meanwhile?
Sorry. Read the full post and noticed that we can't have both.
It's either audio through otg or charging. [emoji30] [emoji31]

That's what I've found, you get EITHER charge OR audio out, not both at the same time. :crying: if anyone knows of a product that can do both please let us all know.

My Note 4 plays through USB DAC and charges at the same time (about 800mA) when connected to Samsung Smart Dock (only 2 of 3 usb ports could host dac). It's important to use 2A Samsung charger and short high quality USB cables. All other docks I tried and longer cables and non-samsung chargers made Note 4 ignore DAC audio output. I also wired smart dock with usb dac in my car so internet radio and even more so flacs sound amazing.

This doesn't help with charging, but in terms of Audio clarity, this is one amazing plug using my car's Aux input/Aux cable straight into my Note 4 microusb port: http://www.amazon.com/gp/product/B00FJSEAZ4/ref=oh_aui_search_detailpage?ie=UTF8&psc=1. It makes my crappy 9 speaker HiFi system in my BMW X5 F15 sound close to the Harmon Kardon sound system - no joke. All the scratchiness at higher volumes is gone. It's all pure clarity.

Note 4 is listed as supported by this cable. Has anyone tried it?

[Q] Samsung smart dock doesn't fully work on s4,Has anyone encounter issues using it?

Hi all
I recently bought samsung galaxy smart dock from aliexpress it was available for $ 35 dollars at the time of purchase.Basically It was samsung smart dock for note 2.On description it was mentioned that it would work with s4 and note 3.I tried using dock on galaxy s4 I9505 but none of the usb ports are working, tried many usb,mouse,keyboard none of them work.I have been experimenting with the dock but only hdmi is working.The phone recognises the dock and when connected it switches to dock mode but doesn't responds to any usb device. Have tried changing data cables and chargers and still not working.
Am I missing any stepstep in using dock,Is smart dock faulty or is this fake smart dock?
I have attached the picture of the dock.

I'm having problems too.
The HDMI on mine works but if I plug anything in the USB ports then the HDMI will flash on and off. If I use mine with mouse and keyboard plugged in but use the screen on the phone (nothing plugged in to HDMI) they work fine. Not sure what to do. It is as if there is not enough power to run all of it.

I have a smart dock and ran into the same trouble. I found that if i plugged in the USB devices before I docked the phone the usb would work great. I have tried a USB keyboard with additional USB ports, a USB mouse, and a wireless USB keyboard/touchpad combo. All have worked fine. I hope this helps.

Hello. I have those... my s4 no charging. Everytin is ok. But not chargin very well

Use geninue samsung charger of 2000 ma. Either the one that was supplied by the phone or the one that came with the smart dock.Try changing data cables.Samsung data cables are little thicker than ordinary cables.
The problem with my smart dock was that it had one broken pin of front connector,that pin was bend when I inspected closely . So I bought another one and all usb,hdmi and charging function is working at same time.I tested using usb 4 gb,keyboard and mouse. Then I plugged speakers and connected to tv .All function were working.:

The problem with my smart dock was that it had one broken pin of front connector,that pin was bend when I inspected closely . So I bought another smart dock and all usb,hdmi and charging function is working at same time.The dock works no matter in which order you use it.I found on the new one that you can plug keyboard, mouse or any usb product before of after putting phone,all works flawlessly.

I had a Smart Dock a while ago and had to return it because after some minor issues with the device not charging, hdmi not working... that usually only needed reconnecting it stopped working, and that happened after having used it few times, I have the feeling they have low build quality. I suggest you try to return it and get other solution.

I got refund from the seller on aliexpress.I came to know that smart dock was itself faulty and it was a copy of original galaxy smart dock.
The connector pin that was bended inwards and was not broken I fixed it later by adjusting the pin with needle and came to know it was not only the issue.I came to kow that if any pin is broken inside connector,Phone will never recognize the dock.In my case phone was recognizing the dock just the dock itself was not responding to any usb device.
The smart dock still then didn't worked although my phone goes to dock mode when connected.Only hdmi and charging works.I returned the product. and bought another one from ebay which is working flawlessly now

I have this dock, I actually bought it from Samsung.com and for some odd reason ended up paying a total of $175usd for it ._.
(original price was $100, shipping ended up as another $30, and then it was wrongfully seized by costumes which nothing short of demanded $45usd or else they confiscate it, I could appeal but that would take ~six months and ... I will face storage charges meanwhile...... which is complete BS.)
As for its functionality:
This thing, on my i9505 works like charm, no need to do any sort of voodoo like putting the USB devices before plugging the device, I simply plug anything I want in any order I want, external 2TB HD? no problems, Logitech G500 mouse? yep, a Filco USB keyboard? aha, 48" SmartTV ? yep.
Everything works, the device "kicks in" some kind of "docking station mode" and everything works from there.
However: this "docking station mode" cannot be avoided or escaped and only apps that show up in it work (stock browser\gallery\mp3\calendar\alarm clock) .. and it works with a small delay, like as if the mouse sits behind a time delay of ~200ms, you know, just slightly faster than 1\4 of a second, same goes for the keyboard, video however plays at the same time was on the phone but UI animations are slightly slowed (both on phone and external display)
This delay is making the overall expriance to be very bad, I can only imagine that the note 2\s3 must feel even slower.
I also have the other simpler adapter that only goes to the power adapter\HDMI (Samsung's as well, from another order, originally bought it for my old n7000\note 1), with that thing the UI is just as slow, everything works essentially the same... video plays wihout issues ETC
What I found out is that with the dock station you cant use any micro-usb extension cable (so that .. the S4 could be used with an extended battery case [or just any non generic thick case]) but with the HDMI adapter it does work (also the female USB adapter, the one that allows you to plug a single device such as thumb-drive\mouse\keyboard - does work with extended micro usb cable)
And last observation:
When using the Sony Expria Z3 Compact (comes with Snapdragon 801) with the Samsung HDMI adapter... it works PERFECTLY, super fast, no delays, UI smooth, and all apps (Everything, really) is accessible... even Blizzard's new Android Hearthstone game... everything, meanwhile the S4 is sluggish as hell and super unfun to use :\
Oh and no phone other than Samsung's works on the docking station, not even old Samsung note 1 (tried nexus 5, lg g2, lg g3, galaxy s1, expria z3 compact, galaxy s2 - only the S4 worked with the dock)

??? Settings>My Device>Accessories to turn off the 'docking mode'
Animations can be a bit sluggish because it's running at 30hz not 60hz like the standalone MHL 2.0 HDMI cable does. Samsung never released an updated version of this dock so I can only assume it wasn't a big hit. (And probably this is one of the reasons! Lack of a landscape support in the touchwiz launcher was a bit of a thumbs down aswell)
I had some problems with HDMI output after a while and initially thought the dock at fault but replacing the usb port in my S4 solved all problems. After about a year of use, dust and grime and crap tends to mess them up. Had the same situation with the S2. Gone past the 2 year point now with my S4, so probably due to replace the port again.
Having a mouse and keyboard plugged in, automatically turns off the device screen, but the touch stills work if you need to do a 'pinch' gesture or similar.
Any full sized S or Note phone after the S3/Note 2 should be compatible with this dock. I had it work for S3 and 4 and Note 2. Not had any others to try them out though. The Note 1 and S2 are only MHL 1.0 so they don't work and I've tried the S4 mini, it won't actually fit, the port on the phone is a slightly different shape (?!)

Thanks for the explanation and feedback Dave =),
The S5 works just the same as an S4, the S4 Active with its inferior specification surprisingly works exactly the same too, furthermore I even tried two other flavors of the S4 (the Verizon version, the 9505 and the 9500) all operates the same.
However, the S6 does not work at all with the dock, regardless of my efforts.
Additionally, during my attempts I found out that if you use a micro USB extension cable (mine was only 2" in length) the dock wouldn't work, I tried using it so I could have the phone laying flat on a table instead of sitting inside the dock (reason was actually due to having an extended 7k battery on one of the above S4s and didn't want to remove it just to fit the phone in the dock ... ended up having to do so as ..... yeah, extension cable = not even charging from the dock)
Oh and with all of the devices that I used with the dock: their screen remind turned on and was displaying a mirror view of the external HDMI screen, unlike what you reported (touch working and no visual cue?)
In my opinion this device, the dock station, is almost as big of a fail as Samsung's wireless keyboard for their SmartTV line ... that doesn't (don't laugh) actually support any of their smart TVs (and does work on any BT enabled android/IOS/windows/linux device, just not on their own TVs despite actually having all the special buttons of their remotes) beyond that point, there's the fact that the keyboard's integrated touchpad is complete garbage (unlike say... Logitech's wireless keyboard's touchpad ...)

Use it correctly...
i have the same dock and all ports work fine. you only have to connect the the charger IN THE PORT and THEN insert the HDMI or USB.

Makeshift USB/HDMI "Dock"...?

I want to take advantage of the S5 MHL capability. Perhaps eventually using the phone as my everyday computer.
So I would need to have usb keyboard and mouse while connected to a monitor.
I have ordered the device pictured below, it reportedly supports the S5 in some kind of half-assed way, meaning that you may have to fiddle with inserting cables in a certain order to get it to work.
This is what I read anyway.
I want to know if any of you have used the Galaxy S5 in such a way. Will my device work? Know of a better solution?
I had some dreams of making my own Diy S5 dock, but I would have to know what kind of electronic/hardware configuration works (if any), as the S5 is different in that it does not support dock mode (Why samsung... why?).

Well I can report that it works. HDMI out works with sound, and it charges while doing so, but the USB port and the card reader does not work apparently.
Obviously the form of the device is a poor match for the Galaxy S5. I had to remove the plastic housing to make it fit, because of the watertight hatch in front of the USB port. Later I will use a USB extender cable.
Hopefully there is a possibility to make OTG (or host mode, or whatever it's called) work.

It appears this device supports the S5

http://www.andromiumos.com/

There is two question marks here.
1) Does S5 support simultaneously operation with OTG active and HDMI output active.
2) Does this gadget also support such a functionality?

I don't know. I've read people claiming that you can use both hdmi & otg at the same time including post's on xda. But i've also read people saying you can't. I certainly havn't seen any video demonstrations.
By the way i currently have my S5 displayed on my monitor using mhl->hdmi adapter and have my pc mouse and keyboard working on the S5 wirelessly with Samsung SideSync. I opened the xda app with the pc mouse and have typed this reply with the pc keyboard. I've done some navigation on the phone, opened and used a range of apps. All is well till i opened firefox and the mouse disappeared from the monitor. It's still displayed and functional on the S5 screen though. Closed firefox and the mouse is displayed on the monitor again.

Therefore your new question this is : Does Firefox (Android) this supports four input devices connected at the same time?
Android Keyboard = 1
External keyboard = 2
Android touch pad = 3
external mouse = 4
And all that active by also active HDMI
I would be surprised if Android OS has such potentials.

I was using Andromium OS app which gives you option to turn off android keyboard and dim S5 screen. Both those functions worked. Andromium OS has 3 menus from start menu. Andromium Apps(browser, file manager), Supported Apps (gmail, youtube), Unsupported apps (all other apps installed on device). PC mouse and keyboard worked fine with Andromium Apps & Supported App. PC mouse and keyboard also worked fine with most unsupported apps i tested except firefox browser and adblock browser. If i get my hands on a bluetooth mouse/keyboard i'll test again to see if it works with firefox browser and adblock browser from monitor.

Personally I am going to use my HP iPAQ FA287 Bluetooth keyboard at S5 ( or at least I will try).
Also ordered one OTG cable (CY U2-166) that hopefully this will offer power to the phone and External HDD, due micro USB (female input for charger cable) and this will become also my mouse input too.
Therefore I am interested for your inquiry / investigation, possibly as much you do, because I do also favor Firefox.

I favour android firefox browser and adblock browser because they are consistent in providing desktop view. I'll provide an update here when i get my hands on a bluetooth mouse & keyboard.

Hi, did this cable charge your S5 while using OTG/USB Host?

My cable did not arrive yet from China.
But even so, in the past days I did some research about finding more details by discovering the factory that makes those cables.
According to real Specifications: (after me correcting errors due bad translation)
High quality Original USB 2.0 Micro-B HOST OTG CABLE
Interface:
Micro USB male: = Output To be connected with OTG complying device ( Your phone or tablet).
Micro USB female: = DC input To charge = Supply of Power due micro USB female connector ( This is only to supply DC voltage to USB A plug this powering hard drives etc etc).
USB female: To connect with USB A device.
Therefore or in conclusion, this cable is not in position to supply power for the phone and the external hard drive.
Later on, that I did the electrical math, I can now explain and the why ? (this cable cannot do both).
By assuming that mobile phone or tablet this requiring 450mA at charging (due PC USB plug), and removable hard-drives (some of them requiring another stable supply of 500mA) the sum this is almost 1A of power.
Manufacturing of OTG cables this requiring from the manufacturer, him to make a product according to OTG cable international standards (compatibility - safety - functionality).
Only if Samsung makes a OTG cable specifically for S5, this will be able for active Host and charging.
All cables available at the moment, them have generic compatibility and non of them will work as we expect or wish.

Samsung hasn't made it easy for us S5 users. Might have to resort to wireless charging at this rate.
Samsung Galaxy S5 Qi Wireless Charging Kit EP-WG900IBEGWW

Just going to throw this out there...
Why not use a bluetooth mouse/keyboard (or even one of those combined ones) with the phone mirroring it's screen to a ChromeCast plugged into your monitor? There's minimal (and I mean you're looking at 10ms) lag - or that's my experience, but I have a really really really fast router etc - and if you're planning on using it essentially as a PC, this setup will work wonders. Plus you can plug the phone in. I've considered using my old S3 in this way.

Charging the S5 through 2A cable would be faster than wireless charging. MHL to HDMI adapter charges the phone as well as mirror your phones screen. I've never used bluetooth mouse and keyboard. Would the S5 support pairing and using both mouse and keyboard at the same time?
By the way there are products for the S3,S4 that support mhl, otg & charging at the same time like the UNITEK Y-2165.

Speaking of compatibility, S5 this is a brother model to Note III.
I do such an assumption due the identical charging system specifications.
From the other hand with all those variants of G900, there is no chance to offer an 100% reliable prediction if you do not test any such OTG product with your own phone.
The link above this is about a Currently unavailable product.
Even so it is interesting that this worked for someone with Note III.

The S5 (or certainly my model, G900T) DOES support everything I mentioned however my bluetooth mouse/keyboard is a 2 in 1 setup with the mouse being a trackpad below the keyboard, similar to a laptop. It mirrors directly to my monitor and I've forced Landscape orientation throughout the OS so it works wonderfully. I've not tried yet with the S3, but I'd assume it'd work the same way. Just need to force the screen to stay always on, pop the screen brightness right down and hide it away in a cupboard and boom, full android computer.
On the original question, a cable must exist but unfortuantely I don't know where.

Definable this is a bad idea the screen to stay always on.
Does phone screen brightness this have any effect at HDMI output (brightness) ?

Nope, but turning it off does. I don't mind it burning out as it's an old device I don't use.

I bet 20 Euros that every one reading this topic he/her, will wonder of why you/he, does not simply turn the brightness down.
Either way, Android it is crippled operating system with out offering much of productivity as it does one regular Windows PC.
Neither a smartphone this is capable for long term gaming, the poor thing does not even have active cooling, and CPU will start slowdown so to protect it self from overheat.
My 0,2 cents, you are in a wrong path.

The link i gave has a few reviews that can give you an idea of what phones are compatible and which ones arn't. Youtube has video demos of the UNITEK Y-2165, unfortunately none for the S5. It appears the desktop dock feature is on the Note III where as samsung removed the dock feature from the S5.

I tell you what, i really like the concept of carring you desktop in your pocket. Can you imagine that, doing your desktop stuff, unplug the phone and head out with everything you did at home on the desktop in your pocket. I know microsoft have a desktop adapter for their Lumia 950 XL phones which changes the layout to desktop mode on the monitor/tv to give you that PC-like experience.

It's a real shame samsung removed dock support from the S5.

HP Elite X3 Lap Dock With Stock Note 9

As I promised, here is my review on using HP Elite Lap Dock X3 with my Note 9
First thing first, the connection quality.
I don't understand why, but it sometimes need several times of reconnecting my note 9 to the lap dock to be recognized properly. Sometimes, my phone recognizes it as only a HDMI monitor, so the keyboard and touchpad doesn't work. On other time, it sometimes shows up in a not FHD screen (it appears blurry and resolution is very low(. Both of this problem can be fixed by reconnecting the phone (sometimes, several times).
Secondly, the audio.
THIS is my main problem and hesitation on using my hp lap dock with a dex phone. On my rooted, Oreo Samsung S8, the audio just doesn't want to output to the HP Lap Dock. And.... It happens as well with my note 9.
Even worse, is the audio rerouting option. When I used my rooted S8, I can reroute the audio output to my S8 using Samsung's Smart Switch app. On my Note 9, when I checked the smartswitch options, there is only a HDMI output and USB Audio output. There is NO option to reroute the audio back to the phone.
*Just a note, my HP Lap Dock audio itself is working. I tested it by connecting it with my Surface Go and it can output sound pretty nice.
Third, the USB-C connector on the right.
Yep, just the same experience with my rooted S8, it doesn't work. Such a bummer.
Well, so far what I've reviewed is the bad side of using HP Lap Dock as dex compaion.. But what are the pros?
First of all, portability.
Well, actually not that portable since this lap dock is quite huge and you'll be getting a better laptop in this size using windows laptop or macbook. But, if you're in a pinch of money after getting sucked dry when pre-ordering your note 9, or you just wanted to show off note 9 capabilities, this is it.
Secondly, the screen and keyboard.
Well, basically this lap dock have a very good screen and keyboard. If you're planning on writing a lot of thing on the go, you can use this.
Personally, eve though I just bought a Microsoft Surface Go, I still prefer the android-dex for my main daily usage. The reason is, android just seems to be a lot practical to use (open youtube? just click the app, no need to type in the browser). The surface go only sits there to ensure whether there is some things that need to be done using .exe applications or complex writing using Microsoft full-fledge office 365 suite.
Hopefully, this review is helpful for anyone planning to use it
*For the record, my hp lap dock system version is at 8.0.11.0.
Anyone using different system version may encounter difference in experience.

Thanks for posting the review! I have messed around a little with my wife's Note 9 on my HP lapdock and I will post a review as well on this thread based on my own personal experience.
By the way, how do you know what system version your lapdock is using?

It is shown when you turn on the lap dock, and it shows whether to connect via USB c (on the left) or wireless display (on the right). On the right side, there is a lap dock software under the lap dock ID on wireless mirroring

I shot a quick raw video of me using my Note 9 with the HP lapdock. The speakers work great and the usb-c ports on the right are also functional. Also worth mentioning is that when I receive a phone call, the game music pauses and the audio re-routes to my bluetooth headset. When I am finished with the call, the sound routes back to the lapdock!

Woah, that's really nice..
Now I wonder why mine doesn't have a working speaker and right port..

Just picked up mine and everything works except for the trackpad. The trackpad mouse movements work fine but the left and right mouse clicks don't work at all. Finger tap for left click and two finger tap for right click work fine but not the physical trackpad buttons. Anyone else getting this too?
Does anyone know if the lapdock charge with a phone charger (QC 3.0 or PD) via the USB-C?

Have tried several chargers (PD 30, 45W chargers and power banks from several manufacturers), still can't find one that charges the lapdock...

Thats a huge dealbreaker for me. Will probably have to return it. The power brick and cable is so insanely bulky kinda takes the point away of a compact device

Hahaha... I agree so much...
Well, for me, I just treat the power brick as my main phone charger as well.. that way, I'm not that bothered by it (since i always carry a backpack to work)..

My experience have been completely negative
The lap dock first I ensured to have the latest firmware T0059 - but the issue is a black screen and constantly rebooting is persistent.
Tried with several devices (Huawei P20 Pro, 2 Galaxy Note 9 -both Exynos, and the HP Elite X3 phone). Only with the Elite phone it worked as expected, keyboard worked fine too.
With Android devices, it was not working and although you could see the keyboard working fine, the screen kept between showing the HP logo then black screen the rebooting. The Touchpad did not work in this mode, only the keyboard and it was reported as an ITE Device(8595) by the keyboard options.
This is all tested using the wired mode and connecting via the usb-c port on the left of the lap dock. Tested also with several cables, some of them confirmed to be Thunderbolt USB-C 3.1 (Gen 2).
In wireless casting, using the Smart View option, I was able to push the video output through Miracast. But the keyboard, although working, it made double key-presses. The Touchpad did not work in this mode either. Audio output worked fine. Funny that connecting an external keyboard worked in this mode and it didn't do any double keypresses.
To make it sort of manageable, in my Exynos Note 9 at least, I had to:
-Push the video wirelessly via miracast & Smart View.
-Connect a keyboard (wireless and wired, doesn't matter) to the Lap dock
-Connect a mouse (I tried wireless) directly to the Note through a USB-C to USB-A adaptor.
The experience was okaish in this wireless mode. But still unhappy. I wish there was a way to debug it.
My test were all with Exynos Note 9, and some comments in Youtube suggest it could be that this only works with Snapdragon based Note 9. I have yet to try with a snapdragon device.

For the note, I personally use an exynos one as well, and the wired mode does work (except for audio and USB ports)..
I think there are still unknown factors that made some of them work, while others don't...

same, this is what primary issue holding me back from getting one.
considering the average battery life on the lap dock, it would be nice to be able to charge it using existing chargers I have around.
if anyone can confirm if they managed to get this charging please post some details of what it was. thanks

I have a Motorola Atrix lapdock. Do you think this can work too?

What's the product code for yours?
This one is Y1M48EA#ABB or #ABE i I'm not mistaken.
And I believe the one the american youtubers and redditors use is V8H07UT#ABA
It could be the third manufacturers building them for HP are diferent.

Mine is V8H07UT#ABA, bought it refurbished from eBay about a year ago...
Working wired connection without USB and audio output..

A very kind redditor confirmed his working Lap Dock is model V8H07UTR#ABA - another American SKU it seems.
It sort of proves my points that American lap dock models work but European models don't. Perhaps different components due to difference in local regulations?
